Tabernanthe iboga has small green leaves. Its flowers are white and pink, while the fruit can be either an elongated oval shape, or a round spherical shape, both having an orange color.
Iboga root has hallucinogenic properties and is very important in the initiation rituals of some African tribes. Ibogaine is classified as a schedule 1 controlled substance in the United States, and is not approved there for addiction treatment (or any other therapeutic use) because of its hallucinogenic and cardiovascular side effects, as well as the absence of safety and efficacy data in human subjects.
